kern.ipc.nmbclusters

Hi. Increasing kern.ipc.nmbclusters on a running box generally causes 
'kmem_map too small' panics, because (I guess) vm.kmem_size is not 
adjusted accordingly. Similarly things go very wrong if I boot with 
'kern.ipc.nmbcluster=0' in /boot/loader.conf. Is one supposed to do any of 
this? :) Just curious.

Cheers
